What Problems Is Your Crawl Space Creating?

You may already be seeing signs:

Excess Moisture

Ground moisture rises unchecked in unsealed crawl spaces which often damages the insulation and wooden joists.

Mold & Musty Odors

If someone in your home is coughing more or experiencing worsening allergies, mold under your home could be the reason

Pest Intrusions

Rodents, roaches, even snakes love a dark, damp crawl space. Once they’re in, they leave behind more than just damage.

Indoor Humidity Issues

That sticky feeling indoors? Fogged windows in summer? It might be moisture creeping up from below your floor.

Weakened Structure

Moisture and rot can silently destroy wood support beams and insulation, putting your homes entire subfloor at risk.

What’s That Dirty Air You’re Breathing?

Up to 50% of the air in your home comes from the crawl space. If it’s moldy or contaminated, that’s what your family is breathing every day.

The Benefits of Crawl Space Encapsulation

Our Crawl Space Encapsulation Process

At Mr. Dirty Ducts we handle the entire project from inspection to final seal.

Step 1

Full Inspection

We’ll identify water intrusion, mold, pest activity, damaged insulation, and compromised ductwork. We’ll clear the debris and address what needs fixing before sealing.

Step 2

Seal Off Gaps & Vents

We close up vents, cracks, wall penetrations, and other entry points. This keeps moisture, pests, and outside air from entering.

Step 3

Install Vapor Barrier

We lay down a durable, 10–20 mil reinforced vapor barrier across the entire crawl floor and up the walls — with full perimeter sealing at every joint.

Step 4

Tape, Seal & Secure

No shortcuts here. We mechanically fasten and tape all seams using industrial-grade materials.

Step 5

Optional Moisture Control Add-Ons

For high-humidity or flood-prone areas, we may recommend:
1. Dehumidifiers
2. Drainage tiles
3. Sump pumps
We never oversell — only what your space requires.

Step 6

Final Walkthrough & Air Quality Check

We inspect our work, measure humidity levels, and ensure everything is sealed tight. You’ll feel the difference — often within days.

Common Questions About Crawl Space Encapsulation

How Much Does Crawl Space Encapsulation Cost?

How Much Does Crawl Space Encapsulation Cost?
Most crawl space encapsulation projects we complete across Middle Tennessee fall between $4,000 and $10,000, based on:
1. Square footage and height of your crawl space
2. Amount of standing water or mold remediation needed
3. Condition of insulation or prior encapsulation work
4. Whether dehumidifiers, drainage systems, or sump pumps are required
All quotes are upfront with no hidden charges, or surprise fees.
We offer written estimates, not sales pitches. Just a local, honest assessment of your home’s crawl space.

What’s the ROI?

Encapsulation delivers real, long-term value:
1. Lower energy bills year-round
2. Increased HVAC lifespan
3. Higher resale value (buyers care about clean crawl spaces)
4. Fewer repairs over time (due to pest and moisture prevention)
Some of our clients have saved $400–$700 per year in utility bills alone.

Is Crawl Space Encapsulation Tax Deductible?

In many cases, yes, especially if energy-efficient insulation, vapor barriers, or moisture control systems are installed. In 2024 and 2025, IRS Form 5695 allows homeowners to claim residential energy credits for qualifying upgrades.
Ask your accountant or tax advisor about current federal and Tennessee-specific programs. We’ll provide the documentation you need.

Do You Offer a Warranty?

Yes. Our encapsulation work includes a one-year workmanship guarantee, and the materials we use (vapor barriers, tape, fasteners) are covered by manufacturer warranties depending on the brand. We’ll walk you through the full protection at the time of your quote.

Are There Alternatives to Encapsulation?

There are, but they’re usually short-term fixes.
1. Venting the crawl space used to be standard. Now we know it increases humidity and energy loss.
2. Insulation-only solutions do not prevent moisture or pests.
3. Liner-only systems often leave gaps and can’t handle long-term moisture.
Encapsulation is the only full-scope solution that addresses air, moisture, insulation, pests, and energy efficiency in one investment for your homes long term investment.
